Bellossom debuts as a Poké Ball Pokémon in Melee. It attacks with Sweet Scent: it starts dancing and releasing a cloud of powder, and any opponents making contact with it fall asleep. The victims cannot move until they are attacked or when Bellossom disappears, making this Pokémon ideal for characters who possess slow attacks with large knockback. Bellossom stays on the stage longer compared to other Pokémon.

Bellossom features as a collectible trophy, unlocked as one of the 100+ trophies that can be collected randomly during normal play, such as in the Trophy Lottery and throughout the various Single-player Regular Matches.

Bellossom

From time to time, these beautiful flower Pokémon will gather in numbers and perform an odd sort of dance to call out the sun. While in the midst of this strange exhibition, their petals brush together to create a peaceful and soothing melody. A Gloom will only evolve into a Bellossom if it's exposed to a Sun Stone. (Pokémon Gold & Silver 10/00)

A Flower Pokémon. After spells of cloudy weather, Bellossom will gather to call out the sun by performing a dance. When exposed long enough to the sun, the leaves on its body will spin around. A Bellossom's Speed is also known to increase with sun exposure. Its main specialty is Grass-type attacks. Also, Bellossom will close its flowers when sleeping.

A Grass-type Pokémon, Bellossom evolves from Gloom, losing its secondary Poison type. It also gets smaller. It's most common to find Bellossom in tropical climates, grouped together and dancing. In Smash Bros., the Sweet Scent from Bellossom can put even the most hardened fighters to sleep.

Two unusual things happen when Gloom evolves into Bellossom: it gets smaller, and it loses its secondary type, Poison, becoming a purely Grass-type Pokémon. These Pokémon are most commonly found in groups in the tropics. Here, the more damage fighters have taken, the longer Sweet Scent keeps them asleep!

While Sweet Scent works differently between Pokémon and Smash, its effect can be seen as consistent since in both series it makes opponents more vulnerable to attacks: in the Pokémon games by lowering their evasiveness, reducing the chance they'll avoid an attack, and in the Smash games by putting them asleep, rendering them open to stronger, normally inaccurate attacks.
